Abstract

A general procedure for texture simulation in multi-pass equal channel angular pressing (ECAP) with capability of applying different processing routes is proposed. The program inputs are the initial texture and the loading condition and the output is texture after deformation. Deformation texture in ECAP of aluminum rod was predicted based on simple shear model for deformation and Visco plastic self consistent model for texture simulation. The simulation was done for two consecutive passes of ECAP and the results were compared with experimental texture measurements. The initial texture of the sample before ECAP was found to play a key role in formation of the final texture and a good agreement between the simulated and the experimental texture was obtained.
